AXGETPUT(1) Linux Programmer's Manual AXGETPUT(1)NAME
axgetput - upload or download files via AX.25 / axspawn Linux login session.
SYNOPSIS
axgetput [-b blocksize] [-i] [-v] [-h] [?] filename
axgetput [-b blocksize] [-i] -s [-v] [-h] [?] [filename]
DESCRIPTION -b blocksize
Set the blocksize (frame length) of transmitted data. Defaults to 256 bytes which matches typical AX.25 network confurations best.
-i Compute CRC checksum only.
.B -s Indicates input from a stream. This option is available only if STDIN is a pipe. The filename argument may be omitted if -s is
given. The length of the file need not to be known.
-v print version and exit.
-h, ? print usage and exit.
axgetput is the actual name of the program. You execute for e.g. bget or bput while axgetput is the common program to which bget and bput
are linked to. axgetput autodetermines which operation mode the user desires.
axgetput sets the pty to be 8bit clean (thus enables binary mode for the file transfer). It requires that the user is logged in through
axspawn(8).
I. #BIN Protocol
bget is used for downloading a file on this system from the unix login shell via his ax25 session to his packet-radio terminal program. The
download "protocol" is the "#BIN" standard known from packet radio mailboxes.
bput does it the other way round: with this comand, the user may upload a file to this computer.
The #BIN protocol provides a CRC consistency check after the file is transfered. The transfer of the file modification time is part of the
#BIN protocol.
II. YAPP Protocol
yget or yput is reserverd for the yapp protocol, which is not supported in this version.
II. DIDADIT Protocol
rget or rput is reserverd for the didadit protocol, which is not supported in this version.
Anyone like to implement yapp and didadit protcols?

TFTP(1) BSD General Commands Manual TFTP(1)NAME
tftp -- trivial file transfer program
SYNOPSIS
tftp [host [port]]
DESCRIPTION
The tftp utility is the user interface to the Internet TFTP (Trivial File Transfer Protocol), which allows users to transfer files to and
from a remote machine. The remote host may be specified on the command line, in which case tftp uses host as the default host for future
transfers (see the connect command below).
COMMANDS
Once tftp is running, it issues the prompt ``tftp>'' and recognizes the following commands:
? command-name ...
Print help information.
ascii Shorthand for "mode ascii"
binary Shorthand for "mode binary"
blocksize [size]
Sets the TFTP blksize option in TFTP Read Request or Write Request packets to [size] as specified in RFC 2348. Valid values are
between 8 and 65464. If no blocksize is specified, then by default a blocksize of 512 bytes will be used.
blocksize2 [size]
Sets the TFTP blksize2 option in TFTP Read Request or Write Request packets to [size]. Values are restricted to powers of 2 between
8 and 32768. This is a non-standard TFTP option.
connect host [port]
Set the host (and optionally port) for transfers. Note that the TFTP protocol, unlike the FTP protocol, does not maintain connec-
tions between transfers; thus, the connect command does not actually create a connection, but merely remembers what host is to be
used for transfers. You do not have to use the connect command; the remote host can be specified as part of the get or put com-
mands.
debug level
Enable or disable debugging levels during verbose output. The value of level can be one of packet, simple, options, or access.
get [host:]file [localname]
get [host1:]file1 [host2:]file2 ... [hostN:]fileN
Get one or more files from the remote host. When using the host argument, the host will be used as default host for future trans-
fers. If localname is specified, the file is stored locally as localname, otherwise the original filename is used. Note that it is
not possible to download two files at a time, only one, three, or more than three files, at a time.
To specify an IPv6 numeric address for a host, wrap it using square brackets like ``[3ffe:2900:e00c:ffee::1234]:file'' to disam-
biguate the colons used in the IPv6 address from the colon separating the host and the filename.
mode transfer-mode
Set the mode for transfers; transfer-mode may be one of ascii or binary. The default is ascii.
packetdrop [arg]
Randomly drop arg out of 100 packets during a transfer. This is a debugging feature.
put file [[host:]remotename]
put file1 file2 ... fileN [[host:]remote-directory]
Put a file or set of files to the remote host. When remotename is specified, the file is stored remotely as remotename, otherwise
the original filename is used. If the remote-directory argument is used, the remote host is assumed to be a UNIX machine. To spec-
ify an IPv6 numeric address for a host, see the example under the get command.
options [arg]
Enable or disable support for TFTP options. The valid values of arg are on (enable RFC 2347 options), off (disable RFC 2347
options), and extra (toggle support for non-RFC defined options).
quit Exit tftp. An end of file also exits.
rexmt retransmission-timeout
Set the per-packet retransmission timeout, in seconds.
rollover [arg]
Specify the rollover option in TFTP Read Request or Write Request packets. After 65535 packets have been transmitted, set the block
counter to arg. Valid values of arg are 0 and 1. This is a non-standard TFTP option.
status Show current status.
timeout total-transmission-timeout
Set the total transmission timeout, in seconds.
trace Toggle packet tracing.
verbose Toggle verbose mode.
SEE ALSO tftpd(8)
The following RFC's are supported:
RFC 1350: The TFTP Protocol (Revision 2).
RFC 2347: TFTP Option Extension.
RFC 2348: TFTP Blocksize Option.
RFC 2349: TFTP Timeout Interval and Transfer Size Options.
RFC 3617: Uniform Resource Identifier (URI) Scheme and Applicability Statement for the Trivial File Transfer Protocol (TFTP).
The non-standard rollover and blksize2 TFTP options are mentioned here:
Extending TFTP, http://www.compuphase.com/tftp.htm.
HISTORY
The tftp command appeared in 4.3BSD.
Edwin Groothuis <edwin@FreeBSD.org> performed a major rewrite of the tftpd(8) and tftp code to support RFC2348.
NOTES
Because there is no user-login or validation within the TFTP protocol, the remote site will probably have some sort of file-access restric-
tions in place. The exact methods are specific to each site and therefore difficult to document here.
Files larger than 33488896 octets (65535 blocks) cannot be transferred without client and server supporting the TFTP blocksize option
(RFC2348), or the non-standard TFTP rollover option.
